I personally avoid using real name everywhere in forums etc, and also avoid giving too much hints about my location to prevent wrong people from recognizing me. Why? Simply because these days, you just cannot be too careful especially if you happen to own a bit more valuable collection than couple of EK2 1914's.
Unfortunately, it's not so impossible, that you get uninvited visitors if you show or tell too much of your collection in public. It's not common, but we do have some horrible examples of this kind of s**t in our and other collecting fields.
I sincerely recommend to everyone, who has - let's say - "more than averagely" valuable collection at home or somewhere else than bank vault - to keep their privacy safe... And even if the goods would be at bank vault behind steel doors (as I do for part of the collection) - you still don't want to have uninvited visitors thinking you might have them at home (or work). Sad to say, but nowadays there is no safe countries or cities in this matter nowadays since borders are pretty open for all kind "entrepreneurers".
Besides, using nicknames in conversations on forums gives you credibility without your real name, if you take part in conversations in respectable way and contribute something to "commonweath".
Just my thoughts of this matter - better safe than sorry
Best regards
